Specific Learning Disability – Decoding
On average, students with a prior SLD diagnosis who received Seeing Stars instruction achieved significant improvements in reading. They made large (statistically significant) standard score changes on all measures. Vocabulary was not a targeted measure of instruction. Additionally, the 17-point percentile increase in Word Recognition and the 18-point increase in Written Language Comprehension puts these students within the normal range (25th–75th percentile). Their pre- to posttest results were statistically significant on all measures.
